Expansion of power rating with 7th-Generation "X Series" RC-IGBT Modules for Industrial Applications

In this report, we describe the series of our newly 7th-Generation "X Series" RC-IGBT Modules for Industrial Applications. IGBT modules have been increasingly required to be smaller in size while exhibiting lower power dissipation and higher reliability. To meet the requirements, we have developed a reverse conducting IGBT (RC-IGBT) modules for industrial applications by using an RC-IGBT that integrates an IGBT and a free wheeling diode (FWD) into one chip. Furthermore, the module greatly reduced power dissipation and thermal resistance and enhanced reliability through optimization based on our 7th-Generation "X Series" technology and RC-IGBT technology. These technology innovations have achieved enhancements such as expansion of rated current, increased power density and miniaturization, all of which were difficult by the combination of conventional IGBT and FWD.
